general character wherein the liability of explosion of the carbide when exposed to moisture is materially reduced without re- 'ducing the value of the carbide. 3

Another object of the invention is to provide a novel and improved process of this character wherein the carbide isv treated with an oil in a manner whereby deteriora- 59 tion of the carbide is prevented and whereby thegas created therefrom will not clog burners or jets through which the gas may flow. Y Furthermore, it is an object of the invention to provide a novel and improved proc- 55 ess wherein the carbide is subjected to treatmentb kerosene and by lard oil.

My improved process involves the .plac- 'ing of the commercial calcium carbide to be treated within a reticulated or perforated container preferably suspended over a suitable vessel, such as a frying pan placed on a stove. Lard oil is poured upon the carbide within the perforated container and ermitted to seep through the carbide to t e pan Application filed man's, 1924. Serial n. 697,158.

or receptacle therebelow. Onl sufiicient $5 amount of lard oil is permitte to .be received within the receptacle or pan to assure a strong vapor. This action is continued until the carbide in the erforated container turns a light brown. T e carbide 40 is then permitted to cool and is plaoedin a bucket or other suitable receptacle and a small amount of kerosene is run through spruce spikes onto the carbide. The spruce has such action on the kerosene to prevent it from slacking the carbide and to cause the same'toserve as a preservative.

1. A process for treating commercial calcium carbide which comprises treating the carbide with lard oil, heating the so-treated carbide while exposing it to the action of the lard oil vapors, allowing the carbide to cool and-then moistening it with kerosene.
